Some states award delegates to candidates on a winner-take-all basis, meaning that the candidate with the most votes in a state is awarded all of that state's delegates. Other states award delegates in proportion to each candidate's share of the primary vote.
Provocative angiography involves a full diagnostic angiogram followed by administration of intra-arterial procoagulant agents to identify an occult bleeding source in patients who have normal test results after lower gastrointestinal bleeding.
Coronary angiography in the setting of coronary artery bypass grafting (CABG) is important diagnostic tool for the evaluation of bypass graft patency in patients presenting with angina or ischemia. Furthermore, coronary interventions in diseased vein grafts are common practice for the treatment of graft atherosclerosis. Angiography in the setting of CABG is more complex and challenging. Before the vein graft angiography is performed, it is very helpful to have the operative report available.
